Peacock Gudgeon (Tateurndina Ocellicauda)

The Peacock Gudgeon is an amazingly attractive, peaceful and unique freshwater fish. Not only do they look amazing, but they are hardy and easy to look after. They do not need certain conditions that are challenging to maintain, and they get along with plenty of other species making them a great member of the community aquarium.

You can keep the Peacock Goby in small groups without any problems. Of course, they will quarrel amongst themselves, but this is always limited to flaring and displaying and makes for a more delightful extravaganza than if you were to keep a couple.

Ideal tankmates for Peacock Gobies could include Rainbowfish from the genus Pseudomugil, Rasboras, Tetras, Corydoras Catfish, and other small peaceful species. However, if you would like to keep them with slightly more territorial fish, such as Dwarf Cichlids, you will need to make sure you provide plenty of tank space.

Peacock Gobies prefer soft and slightly acidic water and plenty of sheltered areas. It would be best to use a dark substrate and floating vegetation as this will help your fish feel safer, leading to a better display of colour. These Gobies require plenty of hiding places, so adding driftwood or bogwood to the aquarium will be greatly appreciated, as would areas of dense planting. Having hiding places in the aquarium will bring your fish out more often.

These fish do not do well in an aquarium with a fast water flow, so it would be best to use gentle filtration. Also, these fish fair better in spotless water, so make sure you perform frequent water changes. Lastly, Peacock Gobies are brilliant jumpers; therefore, you will need a tight-fitting lid on their aquarium.

These fish have elongated bodies. Their heads are rounded, and adult males may develop a nuchal hump on their foreheads, making their round shape even more pronounced. In addition, These fish have a blueish-silvery body and display pink, black and yellow marks along the body, and the fins have a bright yellow thick edge. Females also have a thinner strip of black on top of the yellow portion of the fins.

The sides of their body sport red dotted stripes that run vertically down the fish's entire length, and they also have a yellow abdomen. On either side of the body, there is a single, large black spot at the base of the caudal fin, and this distinct characteristic gives them the peacock name.

Natural Habitat

Sivoli River


In the home aquarium, the Peacock Gudgeon will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is relatively simple to distinguish between a male and female Peacock Goby. The males will be somewhat more colourful and will develop a large nuchal hump on their foreheads and will be slightly bigger than the females. In contrast, females will have a more vividly coloured yellow belly and display a black bar running along the edges of their anal fins. The females also have a more contoured body shape than the round body shape seen in males.
